New angular molecular donor containing two tetrathiafulvalene (ttf) units fused to selenophene: synthesis, x‐ray structure, cyclic voltammetry and conducting charge transfer complex with TCNQ

Extended TTF‐based donor systems based for the first time on selenophene (see Fig.) are reported. Selenophene is an isologue of thiophene but has a stronger electron‐donating ability, a larger size, and a higher polarizability. These factors should lead to materials with increased bandwidth, improved dimensionality, increased electrical conductivity, and reduced on‐site Coulombic repulsion. The one‐pot synthesis of these materials and their complexation with TCNQ are presented (Figure Presented.) .
